  • • Attribute smurfs hiding behind private profiles to their Steam accounts
  • • Analyse Match ID for quick identification of outlier performance against rank percentile averages
  • • Use the "Generate Valve report" button to create a comprehensive, evidence-based summary with match IDs, performance patterns, and win rate analysis

Why smurfing ruins matchmaking

  • • Unfair stomps and mismatched skill levels — new players cannot learn while they're being taken advantage of.
  • • Drives new and returning players away — people in the lower ranks generally play for fun; being stomped isn't fun.
  • • Creates toxic, low-quality games.
  • • Distorts calibration and MMR trends — creates a closed loop where higher-ranked players can't find games because they're in Crusader games.

What rules it breaks

Smurfing and deliberate account manipulation are discouraged and may violate Steam Online Conduct and Dota 2 matchmaking rules.
